CVE-2024-31616

8.8 HIGH

📋 TL;DR

This vulnerability allows attackers to execute arbitrary code on specific RG-RSR10 router models via the common_quick_config.lua file. Attackers can potentially gain full control of affected routers, compromising network security. Only users of RG-RSR10-01G-T(W)-S and RG-RSR10-01G-T(WA)-S routers with specific firmware versions are affected.

💻 Affected Systems

Products:
  • RG-RSR10-01G-T(W)-S
  • RG-RSR10-01G-T(WA)-S
Versions: RSR10-01G-T-S_RSR_3.0(1)B9P2, Release(07150910)
Operating Systems: Router firmware
Default Config Vulnerable: ⚠️ Yes
Notes: Only specific firmware version is confirmed vulnerable. Other versions may be affected but not confirmed.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete router compromise leading to network infiltration, data interception, lateral movement to connected devices, and persistent backdoor installation.

🟠

Likely Case

Router takeover enabling traffic monitoring, credential theft, and use as attack platform against internal network resources.

🟢

If Mitigated

Limited impact if routers are behind firewalls with strict access controls and network segmentation.

🌐 Internet-Facing: HIGH - Routers are typically internet-facing devices, making them directly accessible to attackers.
🏢 Internal Only: MEDIUM - If routers are internal-only, risk reduces but still significant if attacker gains internal access.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Public exploit details available in GitHub gist. Attack appears to require no authentication and has low technical complexity.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: Unknown

Restart Required: No

Instructions:

Check vendor website for firmware updates. If no patch available, implement workarounds immediately.

🔧 Temporary Workarounds

Restrict access to router management interface

linux

Block external access to router web interface and management ports

iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
iptables -A INPUT -p tcp --dport 22 -j DROP

Disable unnecessary services

all

Turn off any unnecessary router services that might expose the vulnerable component

🧯 If You Can't Patch

  • Isolate affected routers in separate VLAN with strict firewall rules
  • Implement network monitoring for unusual router traffic patterns

🔍 How to Verify

Check if Vulnerable:

Check router firmware version via web interface or SSH: show version command

Check Version:

show version

Verify Fix Applied:

Verify firmware version has been updated to non-vulnerable release

📡 Detection & Monitoring

Log Indicators:

  • Unusual access to common_quick_config.lua file
  • Unexpected process execution on router
  • Failed authentication attempts followed by successful access

Network Indicators:

  • Unusual outbound connections from router
  • Traffic to known malicious IPs from router
  • Port scanning originating from router

SIEM Query:

source="router_logs" AND (file_access="common_quick_config.lua" OR process_execution="unusual")
